This study is testing if gabapentin, a medicine, can help kids feel less pain after getting their tonsils removed. Kids aged 3-18 will either get gabapentin or a fake pill (placebo) before surgery. Doctors and nurses won't know who gets which pill to keep it fair (double-blinded). We want to see if those who take gabapentin need less pain medicine and feel better faster. Pain will be checked using scales at 12, 24, and 48 hours after surgery. Younger kids will get Tylenol or Motrin, while teens might get stronger pain medicine. Kids will be called by a nurse for three days to report how they are feeling.

• The study includes 50 children who will have their tonsils taken out.
• Kids will be checked for pain levels at home by phone for three days.
• Those getting gabapentin might need less other pain medicine.
